Compare 11 properties of carbon fiber, aramid fiber and glass fiber
2024-07-16
1. Tensile strength Tensile strength refers to the maximum stress that a material can withstand before stretching. Some non-brittle materials deform before they break, but Kevlar® fibers, carbon fibers, and glass fibers are brittle and break almost without deforming. Tensile strength is measured in force per unit area (Pa or Pascals). Stress is force, and strain is deflection due to stress. Th...

What is a TDS report? What are the differences between TDS reports and MSDS reports?
2024-07-17
All chemicals are told to provide MSDS report before export transportation, and some also need to provide TDS report. What is TDS report? TDS report (Technical Data Sheet) is a technical parameter table, also known as technical data sheet, chemical technical data sheet. It is a document that provides information on the technical specifications and performance of chemicals. TDS reports usually cont...

Why do injection molded parts develop sink marks and dimples?
2024-09-02
(1) Improper control of molding conditions If the injection pressure is too low, the injection and holding time is too short, the injection speed is too slow, the material temperature and mold temperature are too high, the cooling of the plastic part is insufficient, the temperature is too high during demolding, the temperature around the insert is too low, or there is insufficient material supply...

(Ⅰ) How to deal with flow marks on injection-molded parts?
2024-09-27
(1) P: Poor flow of the molten material leads to the formation of concentric flow marks resembling growth rings on the surface of injection-molded parts, centered around the gate. When low-temperature, high-viscosity molten material with poor flow performance is injected into the cavity in a semi-cured, fluctuating state through the injection port and runner, the material flows along the cavity su...

(Ⅱ) How to deal with floating fibers on injection-molded parts?
2024-09-27
Mold temperature too low Cause: If the mold temperature is too low, the melt cools too quickly during flow, causing the glass fibers to not be fully encapsulated by the base resin and float to the surface. Solution: Increase the mold temperature appropriately to ensure the melt has sufficient fluidity to uniformly coat the glass fibers. Regularly check the mold temperature control system to ensure...

The application of high-performance long glass fiber (LFT) materials in explosion-proof cameras
2024-10-28
As we all know, explosion-proof products have extremely specific requirements—explosion-proof ratings, material standards, sealing performance, functionality, certification requirements, and more. Among these, material requirements are particularly stringent. Taking explosion-proof cameras as an example, most currently use stainless steel or cast aluminum alloy for the casing, which can withstand ...

Overview of 8 Non-Destructive Testing (NDT) Methods for Composite Materials
2024-11-01
Composite materials are new materials created through advanced material preparation techniques that combine components with different properties in an optimized manner. In the 1940s, due to the needs of the aviation industry, fiberglass-reinforced plastics (commonly known as fiberglass) were developed, marking the beginning of the term "composite materials." After the 1950s, high-strength and high...
