The advantage of this is that it can enable the new compound to take on properties that the individual materials would not otherwise display on their own. While these materials are less messy and more convenient to use, the resins still contain amines and other compounds, so contact with the skin or eyes must be avoided. Dermal sensitization, which manifests itself as a skin rash, or respiratory sensitization, which elicits an asthmatic reaction and can be quite severe. Flox is mixed in much the same way as dry micro but only about two parts flock to one part epoxy is required. [11] Spider silk also holds its strength at temperatures as low as -40C. Composites have the advantage that they can be formed into almost any shape using the moulding process, but this compounds the already difficult modelling problem. side panels, and the upper sections of the forward and aft upper fuselage. When the lighter composite is transported, or is used in a transport application, there is a lower environmental load compared to the heavier alternatives. On the other hand we used to think asbestos was perfectly safe too. 19. g This by itself might not be a problem except that for every 18-degree (F) rise in temperature, the rate of cross-linking doubles. The first significant use of
